Glaeser et al. (2008) argue that the relative distribution of poor and rich households (HHs) in American cities is “strongly” explained by the spatial location of the cities’ public transportation (PT) networks. Among their claims: 1) The broad distribution of poor and rich HHs in the...

This paper presents estimates of time-varying income elasticities of demand for energy and metal commodities. The analysis finds that the elasticities are close to unity, evaluated at world median per capita income levels. Furthermore, the estimates confirm that as income rises, demand growth...

Wagner's Law holds that the relative size of public sector increases with the growth of per capita income. The aim of this study is to investigate the validity of Wagner’s Law in Iran. We test the Wagner’s Law by incorporating a vector Autoregression model (VAR) and vector error correction...

We use a randomized controlled trial to study the effect of large income changes, through unconditional cash transfers, on the food share of expenditures and consumption of calories among poor households in rural Kenya. Our preferred estimate of the food elasticity following USD 709 transfers is...

The possible non linearity of the income elasticity of child labour has been at the centre of the debate regarding both its causes and the policy instruments to address it. We contribute to this debate providing theoretical and empirical novel results. From a theoretical point of view, for any...

Sectoral heterogeneity has been shown to affect country-level welfare gains from trade that can be calculated by sector-specific trade elasticities and home expenditure shares. However, empirical analyses of multi-sector models are restricted to a limited number of countries and sectors, mostly...

This paper analyzes the effect of local income taxation on taxable income, inequality and internal migration in Italy using two tax reforms and several administrative data sources. These reforms, introduced in 2007 and 2011, granted municipalities the authority to switch from a flat to a...

This study revisits the import demand function for Turkey using the newly defined national income data and examines the evolution of the income and price elasticities over time. In this respect, demand functions are estimated for the total imports and its subcomponents separately, and the...
